Embodiment Construction

[0111] First, the technical terms and application scenarios involved in this application are introduced.

[0112] In a single-carrier scenario, taking LTE as an example, the network device configures frequency resources, which are used for downlink transmission and uplink transmission, and there is a predefined correspondence between the uplink frequency resources and the downlink frequency resources. For example, for frequency division duplex (frequency domain duplex, FDD) spectrum, downlink transmission and uplink transmission use different frequency resources. For time-division duplex (time domain duplex, TDD) spectrum, downlink transmission and uplink transmission use the same frequency resource. At this time, the network device performs downlink transmission and the communication device performs uplink on the same frequency domain resource based on time division multiplexing. transmission.

[0113] In the CA scenario of NR, when the network device configures frequency re...

Abstract

The invention discloses a carrier wave state indicating method and device used to support activation and deactivation of carrier waves in NR. The method comprises that a communication device communicates with network equipment in the first uplink carrier wave based on the first downlink carrier wave, the communication device receives carrier wave state indication information sent by the network equipment, the carrier wave indication information indicates carrier wave states of M carrier waves corresponding to cells, providing services for the communication device, of N network equipment, the carrier wave states include activation and deactivation states, the carrier state indication information indicates the first downlink carrier wave in the deactivation state and the first uplink carrierwave in the activation state, and the first downlink and uplink carriers waves are selected from the M carrier waves.<{EN11}>The method can be used to realize carrier wave activation and deactivationflexibly in the NR.<{EN11}>The method can be used to realize carrier wave activation and deactivation flexibly in the NR. The method can be used to realize carrier wave activation and deactivation flexibly in the NR.<{EN11}>The method can be used to realize carrier wave activation and deactivation flexibly in the NR.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a carrier state indicating method and device. Background technique [0002] The continuous growth of smart terminal users, the continuous increase of user traffic and data throughput, put forward higher requirements for communication speed. However, due to the shortage of wireless spectrum resources, it is difficult to find continuous large bandwidth for mobile communication. Therefore, the Carrier Aggregation (CA) technology is introduced into the Long Term Evolution (LTE) communication system, and multiple continuous or discontinuous spectrums are aggregated to solve the technical problem of mobile communication for large bandwidth. demand, while also improving the utilization of fragmented spectrum in the wireless band. [0003] In the fifth generation (the 5th generation, 5G) new wireless communication protocol (new radio, NR), CA is also a nece...
